Hillsborough Window Cost Calculator

Calculate how much you can expect to pay for window installation and replacement in Hillsborough, NH using our customized window cost calculator.

Estimated Window Cost:
161 homeowners have requested a free estimate in the last 3 days.

Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.

How Installing Energy-Efficient Windows in Hillsborough Saves You Money

Energy-efficient windows can offer benefits in several ways. Here are some reasons you may want to take the plunge and make the switch:

  • Better temperature control in your home: When you live in a place like Hillsborough where the summers can be pretty warm, you usually need to depend on your air conditioner to keep your house cool. Energy-efficient windows can cut back on how much cool air is lost through your windows when cooling your home.
  • Save on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Switching to energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.
  • Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.

Estimated Cost of Window Replacement in Hillsborough

Let's go over the cost of installing new windows and the types of services you may need for your home.

How Much Do New Windows Cost?

Typically, homeowners in Hillsborough can anticipate that most replacement window installations will cost between $250 and $1,200, with the average cost sitting at around $600. This is because of the fact that the cost of window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.

Whether or not you opt for energy-efficient windows is another factor that will affect the cost. These will typically cost more than other windows, but on the other hand, you can save about $463 a year on your energy bills in Hillsborough.

We recommend requesting free quotes from multiple window installers to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

There are typically two kinds of window installation services: full-frame and pocket installations.

A full-frame installation is a total window replacement. It involves removing the old window, the sill, and the exterior and interior trim. It also involves additional materials, like insulation and drip edges, which raise the total cost of the project. It's also worth noting that it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

If you're hiring a reputable window installation company, your company can advise you on the best type for your project. In Hillsborough, the decision will mostly be influenced by the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Hillsborough

EcoWatch reviews are different from other reviews, as we assess these companies through a sustainability lens. We have decided to evaluate the top window replacement companies in Hillsborough primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the right window installation company near you.

Work Quality

When installing new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand of window you choose. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don't have good things to say about their experience with a certain installer, you won't see it featured on EcoWatch.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers' prices, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed previously, windows are a hefty investment, so you'll want to make sure that investment is well protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

Hillsborough, NH Window Replacement FAQs

How much should a window install cost?

The national average cost to install a single window is around $600 but can range from $200 to $1,200, based on several factors. The price is often dependent on the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

What are the most common kinds of replacement windows?

The most common types of windows for homes are slider windows, picture windows, awning windows, transom windows, bay windows, double-hung and single-hung windows and casement windows.

Can I install my own windows?

If you're handy and have experience with similar home improvement projects, it's possible to install your own windows. However, if you don't have the time or experience, we don't recommend doing it on your own.

When is the best time of year to replace windows?

While you can install windows any time of year, warmer weather is typically better for replacing windows. In addition, it shouldn't be raining, since rain can make the installation more difficult.
